Pengda Recycling Used Plate and Frame Filter Press

The structure of a filter press consists of three parts:

The frame is the basic component of the filter press, with thrust plates and compression heads at both ends. The two are connected by large beams on both sides, which support the filter plate, filter frame, and compression plate. To meet advanced hygiene requirements, the rack needs to be wrapped in stainless steel. Stainless steel technology can be used as a reference, and its quality can meet the needs of European customers.

A、 Thrust plate: It is connected to the support to seat one end of the filter press on the foundation, and the middle of the thrust plate of the box filter press is for feeding

Holes, there are four corners and four holes. The holes in the upper two corners are for the inlet of washing liquid or compressed gas, and the lower two corners are for the outlet (whether it is a dark flow structure or a filtrate outlet)

b、 Compression plate: used to compress the filter frame of the filter plate, and the rollers on both sides are used to support the compression plate to roll on the track of the main beam.

C、 Main beam: It is a load-bearing component that can be coated with rigid polyvinyl chloride, polypropylene, stainless steel coating, or new anti-corrosion coatings according to the requirements of anti-corrosion in the usage environment.

Manual compression, mechanical compression, hydraulic compression.

A、 Manual compression: It is to use a spiral mechanical jack to push the compression plate to compress the filter plate.

B、 Mechanical compression: The compression mechanism consists of an electric motor (equipped with an overload protector), a reducer, a gear pair, a screw, and a fixed part

Composed of nuts. When compressing, the motor rotates forward, driving the reducer and gear pair to rotate the screw rod in the fixed nut, and pushing the compression plate to compress the filter plate and filter frame. As the clamping force increases, the motor load current increases. When it reaches the current value set by the protector, the maximum clamping force is reached, and the motor cuts off the power and stops rotating. Due to the reliable self-locking helix angle of the screw rod and fixed nut, the clamping state during the working process can be reliably guaranteed. When it retracts, the motor reverses. When the pressure block on the clamping plate touches the travel switch, it retracts and stops.

C、 Hydraulic compression: The hydraulic compression mechanism consists of a hydraulic station, an oil cylinder, a piston, a piston rod, and a connection between the piston rod and the compression plate

The structure of the Haflan card hydraulic station includes: motor, oil pump, relief valve (regulating pressure), directional valve, pressure gauge, oil circuit, and oil tank. When hydraulic compression mechanical compression is applied, high-pressure oil is supplied by the hydraulic station, and the component chamber composed of the oil cylinder and piston is filled with oil. When the pressure is greater than the frictional resistance of the compression plate, the compression plate slowly presses the filter plate. When the compression force reaches the pressure value set by the overflow valve (displayed by the pressure gauge pointer), the filter plate, filter frame (plate frame type) or filter plate (box type) is compressed, and the overflow valve begins to unload. At this time, the motor power is cut off, the compression action is completed, and when it returns, the directional valve changes direction, and the pressure oil enters the rod chamber of the oil cylinder. When the oil pressure can overcome the frictional resistance of the compression plate, the compression plate begins to retreat. When hydraulic compression is set to automatic pressure holding, the compression force is controlled by an electric contact pressure gauge. The upper and lower limit pointers of the pressure gauge are set to the values required by the process. When the compression force reaches the upper limit of the pressure gauge, the power supply is cut off and the oil pump stops supplying power. Due to possible internal and external leaks in the oil system, the compression force decreases. When it reaches the lower limit pointer of the pressure gauge, the power supply is turned on and the oil pump starts supplying oil. When the pressure reaches the upper limit, the power supply is cut off and the oil pump stops supplying oil. This cycle ensures the compression force during the process of filtering materials.
